CNMG090308 AH6225 CNMG ISO 090308 rhombic turning insert, PVD-coated carbide — Tungaloy

The CNMG090308 AH6225 is an ISO rhombic turning insert designed for reliable external and internal turning of stainless steel under varying machining conditions.

• ISO rhombic insert CNMG 09
• PVD-coated carbide AH6225 for stainless steel
• 0.8 mm corner radius, 80° lead angle
• Cylindrical hole, double-sided chipbreaker

Reliable edge performance for demanding stainless steel turning

The combination of PVD-coated carbide and the AH6225 grade is aimed at providing a balance between sharpness and edge stability when machining stainless steel. The PVD layer increases wear resistance and reduces built-up edge formation, so tool life is extended under medium cutting conditions. Because the grade was developed for fluctuating conditions, surface finish consistency is improved without sacrificing productivity, and the life of the insert is made more predictable for shop planning.

Smooth integration with established ISO tool systems

Designed to the ISO standard, the rhombic geometry and the standard dimensions ensure straightforward fitting into compatible toolholders. Compatibility is determined by form, clearance angle, tolerance class, fastening method, size and thickness, which are standardised for this series. The insert is intended to be used with an appropriate external holder or boring bar, a supporting shim/clamp set and replacement screws, allowing rapid changeovers and minimising downtime on the machine.

Predictable chip control and dimensional security

The double-sided chipbreaker promotes consistent chip formation across a range of feeds, helping to avoid long stringy chips and reducing interruptions. The 0.8 mm corner radius provides a compromise between strength and profile definition: it supports edge robustness for medium cuts while producing a controlled cutting edge radius that benefits surface finish. The rhombic form and 80° lead angle lend stability in both external and internal turning operations, enhancing process reliability in production runs.

Practical workshop benefits and handling

The insert is manufactured from carbide with a PVD coating and is double-sided, so one insert provides two cutting edges before indexing. The plate thickness of 3.18 mm and the cylindrical hole are designed for secure clamping, reducing the risk of movement under load. Traceable article and manufacturer SKUs support inventory control and reordering, while the standardised format simplifies tool management across machines. For customers seeking a robust, universal solution for stainless steel turning, this insert offers a pragmatic balance of performance and usability.

FAQ

What materials is this insert suited for?
The CNMG090308 AH6225 insert is a PVD-coated carbide grade developed primarily for stainless steel machining and is suitable for medium cutting conditions where a sharp, stable edge is required.

Can the insert be used for both external and internal turning?
Yes, the rhombic CNMG geometry and an 80° lead angle make the insert appropriate for both external and internal turning applications when used with a suitable holder.

How does the chipbreaker affect machining performance?
The double-sided chipbreaker on this Tungaloy insert supports controlled chip formation, reducing the risk of long chips and improving process reliability during continuous production.

What does the 0.8 mm corner radius mean for my parts?
A 0.8 mm corner radius offers a compromise between edge strength and the achievable surface finish: it increases edge robustness for medium cuts while still producing an acceptable profile on the workpiece.

Which identifier should be used when reordering this insert?
Use the article number 6903155 or the manufacturer SKU TUN6903155 to ensure the correct CNMG090308 AH6225 Tungaloy insert is supplied.
